Improvement in lamp-wicks



UNITED STATES PATENT QFFICE.

WILLIAM H. LYON, OF TROY, NEW YORK.

IMPROVEMENT IN LAMP-WICKS.

Specification forming part of Letters Patent No. 180,482, dated August1, 1576; application filed June 27, L376.

To all whom it may concern:

Be it known that I, WILLIAM H. LYON, of the city of Troy, county ofRensselaer, and State of New York, have invented a new and usefulImprovement in Wicks and Burners for Torches and Lamps and that thefollowing is a full, clear, and exact description .of theinvention,.reference being had to the accompanying drawings, which forma part of this specification, and in which- Figure 1 is a verticalsection, showing the tube with its Wick-sustaining rods located in atorch or lamp. Fig. 2 is a perspective view of the tube, and Fig. 3 ahorizontal section thereof in the line 00 :r of Fig. 2.

The object of my invention is to provide an economical, safe, andimperishable wick and burner for torches and lamps.

I make the tube or burner A of tin or other metal, of the proper lengthto reach the bottom of the cup or lamp. The tube is pierced with smallholes near its bottom to admit the oil or fluid into it. It is thenfilled with asbestus, crushed, but not so fine as to destroy the fiber,packed closely" to form the wick. Within this tube are two or more thinpieces of metal or tine wire, b b, hooked onto the bottom of the tube,and passing through it, and bent over the asbestos at the top of thetube to hold it securely in place.

The bottom of the tube rests upon the bottom of the cup, and the oil orfluid is drawn through the openingsin the tube into the as bestus, whichproperly strains the oil or fluid,

and then to the point of combustion.

A wick made entirely of asbestos, and secured in a tube, as hereindescribed, will be so little affected by the flame and heat that it maybe considered imperishable.

No oil or fluid can escape from the tube through the asbestos withoutbeing consumed, and there is, therefore, no waste. Moreover, no more oilor fluid is drawn through the tube than is necessary to maintain a fulland free flame; consequently an equal quantity of oil will maintain anequal flame from a tube or wick'constructed as herein described muchlonger than from the tubes and wicks made in the ordinary manner.

I am aware that asbestos has before been used for lamp-wicks, and I donot desire to be understood as making any claim thereto 5 but What Iclaim as new, and desire to secure by Letters Patent, is-- A wick madeof asbestus or other imperishable material, in combination with a tubehaving one or more openings to admit the oil or fluid, and the metalhooks b b, to keep the asbestus properly in place.

In witness whereof-I have hereto set my hand'this 22d day of June, 1876.

WILLIAM H. LYON. Witnesses: W. Oseoon, H. D. HUTTON.
